St. Louis County started separate record keeping from St. Louis City in 1877. It was not until December 1878, however, that the county established a new courthouse in the new county seat of Clayton, Missouri.
Near the central, western boundary of the city is Forest Park, site of the 1904 World's fair, the Louisiana Purchase Exposition of 1904, and the 1904 Summer Olympics, the first Olympic Games held in North America. At the time, St. Louis was the fourth most populous city in the United States. The Missouri River forms the northern border of St. Louis County, exclusive of a few areas where the river has changed its course. The Meramec River forms most of its southern border.
